The wide supply range (2.25V–3.6V) lets it run directly from a 2.5V or 3.3V rail without an intermediate regulator, simplifying the power tree. ## Package and footprint for 6-SMD layout Housed in a 7.00 mm x 5.00 mm 6-SMD package with an exposed pad (0.90 mm seated height). The 0.276\" x 0.197\" footprint is common across the DSC1122 series, so a single layout can accommodate multiple frequency variants. Listed as Active with no end-of-life notice from Microchip.","metaTitle":"DSC1122AI2-156.2500T MEMS XO, LVPECL 156.25 MHz, Active","metaDescription":"Microchip DSC1122AI2-156.2500T: 156.25 MHz LVPECL MEMS oscillator, ±25 ppm stability, -40°C to 85°C, 6-SMD.
